Learn vapor pressure definition and discover a few common examples which involve vapor pressure. Know and use formulas that involve the use of...
Under these conditions, the solute depresses the vapor pressure of the solution drop with the effect that solvent evaporates from the pure solvent drop and condenses onto the solution drop. The instrumentation detects the difference in temperature of the drops. Because colligative properties depend on...
Vapor pressure increases with increasing temperature. It decreases with the addition of a nonvolatile solute because the solvent constitutes a smaller proportion of the liquid, and the nonvolatile solute occupies space without contributing to vapor pressure. The greater the concentration of solute, the...
A model describing the operation of the vapor pressure osmometer has been developed to account for the solute dependence of the calibration constant. This model envisions the existence of a diffusion-controlled surface concentration that differs from the concentration of the drop as a whole. Three ...
Further, as a consequence of this quadratic behavior, the vapor pressure of semiconductor nanoparticles rises more slowly with decreasing size than would be expected. In addition, the melting point of these nanoparticles will experience less suppression than experienced by metal nanoparticles with ...
On one hand, the increase of temperature can improve the saturated vapor pressure of the solute; on the other hand, the high temperature also reduces the density of the supercritical fluid, namely, reduce the solubility of the solute. Particle formation by supercritical fluid extraction and expansi...
Which of the following factors affect the vapor pressure of a liquid? (a) Amount of liquid. (b) Atmospheric pressure. (c) Addition of solute. (d) Temperature. (e) Type of liquid surface. (f) Area of t What type of vapor pressure is measured when a dynamic equilibrium ...
the most significant include volume changes due to evaporation and management of vapor pressure during pipetting steps. Rapid evaporation of solvent and concurrent increases in solute concentration due to high vapor pressure can be managed by lowering the temperature (and subsequent vapor pressure) of ...

Vapor Pressure: The vapor pressure of a substance is a bulk property that describes the amount of pressure exerted by the gas molecules that are in equilibrium with a liquid or solid. The vapor pressure is affected by certain factors...
